W1 THESE Patented F b, 16, 1932 PATENT OFFICE FRED J. KLIST, OF SYRACUSE, NEW YORK COVER-ALL GA]? Application filed December This invention relates to certain new and useful improvements in cover-all caps.

The primary object of the invention is the provision of a cover-all cap for milk bottles and the like which can be rapidly and economically produced,-applied and secured to a bottle without the provision of separate fastening means, and which acts to protect the top of the bottle from dust and foreign matter, and prevents the removal of all or any portion of the contents of the bottle and the substitution of other or inferior material for that removed without the fact that the cap has been removed becoming obvious.

Other objects and advantages will appear from the following description, taken in connection with the accompanying drawings, in which Figure l is a perspective view of a coverall cap of this invention applied to the top of a bottle. 1

Figure 2 is a section on line 22, Figure 1. Figure 3 is a horizontal section through the bottle and the skirt of the cover-all cap. Figure 4: is a plan'view of the paper blank from which the cap is formed.

Figure 5 is a view similar to Figure 2 of a slightly modified form of the invention.

The cover-all cap is vdesigned for use with and application to a bottlehaving an exter-.

nal head 1-' at its upper end and a contracted neck -2 below the bead and the paper disk which includes a central portion 3 adapted to cover the upper end or mouth'of the bottle and a skirt portion 4- contracted about the neck of the bottle by the formation therein of a plurality of-plaits 5 which gradually increase in width as they extend downwardly along the skirt, and

40 are preferably, as shown, folded fiat against 7, 1929. Serial No. 412,534.

' tial contact with the body of the skirt and in the space between the body of the skirt and the neck of the bottle, and is confined by the body of the skirt and acts to lock the plaits from unfolding, and as the folded portion lies beneath the bead of the.bottle at the contracted neck and is of less diameter than the greatest external diameter of the bead, the cap cannot be removed without un- 5 folding the plaits, thereby destroying the effective holding or locking capacity of the reversely folded edge 6 In this manner and without the use of separate fastening means "the plaited skirt is held in its folded plaited condition to maintain the cover-all cap upon the bottle.

A'perhaps preferred form of locking flange is illustrated in Figure 5 in which the lower edge of the skirt instead of being completely folded back in a flange 6 of one thickness, isformed in a V-shaped flange 7 of two thicknesses ofthe material of the skirt positioned between the body of the skirt and the bottle neck below the bead to more securely hold the cap against removal.

Altho I have shown and described a specific form of cover-all cap and preferred details of constructionand arrangement of the same, I do not desire to restrict myself to the exact details of form, construction or arrangeinent, as various changes and modifications may be made within the scope of the appended claims.

., I claim:

1. The combination with a bottle having an annular bead and a contracted neck below the bead, of a cover-all'cap formed from a blank with a central portion to cover the mouth of the bottle and a skirt to surround the bottle neck, the excess material not required for the skirt 'being formed into a plurality of plaits widening downwardly to contract the skirt about the bottle neck and the lower edge of the skirt being folded back upon the body of the skirt below the bottle bead and in the space between the skirt and the bottle neck to maintain the plaits in folded position with the infold of the skirt cooperatin 5 with the bottle bead to prevent removal 0 the cap.

2. The combination with a bottle having an annular bead and a contracted neck below i the bead, of a cover-all cap formed from an imperforate paper blank with central portion to cover the mouth of the bottle, and a skirt to surround the bottle neck, the excess material not required for the skirt being formed into a plurality of plaits folded flat 5 against the body of the skirt and widening downwardly to contract the skirt about the bottle neck and the lower edge of'the skirt being folded back upon the body of the skirt below the bottle bead and in the space between the skirt and the bottle neck to maintain the plaits in folded position with the infold of the skirt cooperating with the bottle bead to prevent removal of the cap.

3. The combination with a bottle having an annular bead and a contracted neck below the head, of a cover-all cap formed from a paper disk with a central portion to cover the mouth of the bottle, and a skirt portion to surround the bottle neck, the excess material not requiredforthe skirt being formed into a lurality of plaits folded flat against the b0 y of the skirt to contract the skirt about the bottle neck and the lower edge of the skirt and plaits being folded back below 5 the bead and around the contracted portion vof the bottleneck to maintain the plaits in folded position and said skirt end and fold acting in cooperation with thei-rbottle neck and bead to prevent removal of the cap with- 40 out distortion of the folded plaits.

- In witness whereof I have hereunto set my hand this 26th day of November, 1929.

- FRED J. KLIST.
